BTC Quality Assurance & Standards 3 — Questions and Answers
Question 1: In a medical equipment management program, what does 'risk-based maintenance' prioritize?
- Allocating maintenance resources based on the device's risk to patient safety (Correct answer)
- Performing maintenance only on devices that have recently failed
- Reducing overall maintenance costs regardless of device criticality
- Following a fixed time-based schedule for all devices equally
Correct answer: Allocating maintenance resources based on the device's risk to patient safety
Risk-based maintenance focuses resources on devices where failure would pose the greatest threat to patient safety, using risk scoring to prioritize schedules.
Question 2: Which document type formally describes the step-by-step process a technician must follow when performing a preventive maintenance task?
- Standard Operating Procedure (SOP) (Correct answer)
- Purchase Specification
- Equipment Inventory Log
- Incident Report Form
Correct answer: Standard Operating Procedure (SOP)
An SOP provides detailed, standardized instructions ensuring that maintenance tasks are performed consistently and in compliance with manufacturer and regulatory requirements.
Question 3: Under JCAHO/TJC Environment of Care standards, a hospital's medical equipment management plan must include:
- Criteria for identifying, evaluating, and maintaining equipment on the inventory (Correct answer)
- A list of all equipment purchased in the last fiscal year
- Monthly reports on equipment downtime submitted to administration
- Annual replacement budgets for all life-critical devices
Correct answer: Criteria for identifying, evaluating, and maintaining equipment on the inventory
TJC EC.02.04.01 requires that the medical equipment management plan define criteria for identifying, evaluating, and creating an inventory with maintenance activities.
Question 4: An audit trail in a computerized maintenance management system (CMMS) is important because it:
- Provides a verifiable record of all actions taken on a work order for compliance purposes (Correct answer)
- Allows technicians to edit previous records without leaving a trace
- Reduces the number of paper documents needed in the department
- Automatically schedules future preventive maintenance tasks
Correct answer: Provides a verifiable record of all actions taken on a work order for compliance purposes
An audit trail captures every change, approval, and action in a CMMS, supporting regulatory compliance, root cause analysis, and accountability.
Question 5: IEC 60601-1 primarily establishes requirements for:
- General safety and essential performance of medical electrical equipment (Correct answer)
- Software lifecycle processes for medical devices
- Sterilization methods for reusable surgical instruments
- Clinical trial protocols for new medical technologies
Correct answer: General safety and essential performance of medical electrical equipment
IEC 60601-1 is the fundamental international standard defining general safety and essential performance requirements for medical electrical equipment.
Question 6: A 'control chart' in statistical quality control is used to:
- Monitor process variation over time and detect when a process is out of control (Correct answer)
- List all known defects in a batch of medical supplies
- Calculate the mean time between failures for a device fleet
- Schedule calibration intervals for test equipment
Correct answer: Monitor process variation over time and detect when a process is out of control
Control charts plot process data over time against control limits, enabling detection of unusual variation that signals a process may be out of statistical control.
Question 7: Which of the following is an example of a preventive action in a biomedical QA program?
- Updating a maintenance checklist after identifying a potential failure mode before any incidents occur (Correct answer)
- Replacing a failed component in a ventilator after a patient incident
- Retraining a technician after they made an error on a work order
- Issuing a corrective action request following a failed audit
Correct answer: Updating a maintenance checklist after identifying a potential failure mode before any incidents occur
Preventive action addresses potential problems identified before they occur, such as updating procedures in response to a risk analysis finding.
